ASP.config文件和Azure设置之间存在混淆。Net core web app

通常在ASP中。NET Core我们使用 appsettings.json https://joonasw.net/view/asp-net-core-1-configuration-deep-dive .

所以你会有一个appsettings。json文件如下:

{
  "ConnectionStrings": {
    "MainDb": "Data Source=.;Initial Catalog=MainDb;Integrated Security=True"
  }
}

IConfiguration 中的对象 Startup :

public class Startup
{
    public Startup(IHostingEnvironment env)
    {
        var builder = new ConfigurationBuilder()
                .SetBasePath(env.ContentRootPath)
                .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);
        Configuration = builder.Build();
    }

    public IConfiguration Configuration { get; set; }

    public void ConfigureServices(IServiceCollection services)
    {
        string connStr = Configuration.GetConnectionString("MainDb);
    }
}

GetConnectionString("name") 实际上是 Configuration.GetSection("ConnectionStrings")["name"]
